ABSTRACT:
A packing material has a plurality of separable layers of pliable material. Each layer has a region containing a plurality of domes in a pattern extending in two directions. The plurality of domes are nested together in the region. The plurality of domes each have a top, a base and a side extending from the top to the base at an angle of divergence exceeding 10°. The plurality of domes have a dome height of at least ⅛ inch. Adjacently nested pairs of the domes have between them an overhead gap no greater than 10% of the dome height. The plurality of separable layers with the plurality of domes can be separated and disoriented to occupy a larger volume. These separable layers may be discrete layers, pleats in a web, or sections of a web.
